摘要： In one aspect, a computerized-method of a distributed database includes the step of providing a first data partition with a set of data. The method includes the step of providing a second data partition with a replica of the first set of data. The method includes the step of identifying a client application accessing the first data partition and the second data partition. The method includes the step of performing a reclamation operation on the second data partition. The method includes the step of informing the client application that a read operation is prohibited during the reclamation operation.

摘要： In one exemplary aspect, a method of a distributed database system includes the step of detecting that a database node departed from a database cluster. A consensus-based voting process is implemented utilizing all of a set of other database nodes remaining in the database cluster. A cluster configuration is determined with the consensus-based voting process. The cluster configuration includes a new list of the set of other database nodes remaining in the database cluster. The data is automatically rebalanced among the set of other database nodes remaining in the database cluster according to the cluster configuration. Optionally, the consensus-based voting process can include a Paxos algorithm. The database cluster can be a Not-Only SQL (NOSQL) distributed database cluster.

摘要： In one exemplary aspect, a method includes building a data index from a set of data from a client application in a distributed database system. The data index is optimized for operation in a DRAM data-storage device, and wherein the data index is built to use a set of fix-sized blocks that fit a DRAM device block size. The data index is maintained in the DRAM data-storage device. An SSD data-storage device is used to persistently store the data referenced by the data index in the DRAM data-storage device, and wherein the data and the metadata are stored in the SSD data-storage device in a log-based format.

摘要： In one exemplary embodiment, a method of a distributed database system includes the step of receiving a database transaction with a node of the distributed database system. A priority of the database transaction is determined. A load of a transaction queue of the node is determined. The execution of a database transaction is delayed if the load of the transaction queue is greater than a first-water mark. The database transaction is delayed for a specified period. A portion of the database transaction is execution after the specified period. It is determined if the load of the queue is below a second-water mark after the specified period. A remaining portion of the database transaction can be processed if the load of the queue is below the second-water mark.
